Screw rods 72 are vertically and threadedly installed on the top ends of the support seat bodies at the two sides of the top end of the rack 1, and the lower ends of the screw rods 72 are movably connected to the top ends of the corresponding slide seats 71. This sliding connection provides the dust suction hood 73 with flexible height adjustment function, and the height of the dust suction hood 73 can be accurately adjusted by rotating the screw rods 72. The beneficial effect of this design is that the distance between the dust suction hood and the slitting roller can be optimized in real time according to the thickness of the ceramic diaphragm, the wear condition of the slitting cutter, and the actual dust generation amount and distribution, so that the dust suction hood is always in the best dust suction position, thereby ensuring efficient dust collection effect and effectively reducing the influence of dust on the equipment and the quality of the ceramic diaphragm.

[0031] Further, a guide roller 3 is rotatably installed above the rack 1 and inclined downward at the two sides of the slitting roller 4, and between the set of conveying rollers 2 and the material collecting roller 5. A transmission mechanism 6 is arranged on one side of the rack 1.

[0032] Further, in the above technical solution, the transmission mechanism 6 includes a motor 63, the motor 63 serves as the power source of the entire transmission mechanism 6, and provides stable power output for the rotation of the material guide roller 3 and the slitting roller 4, the motor 63 is fixedly installed on the lower side of the rack 1, and the same end of one material guide roller 3 and the slitting roller 4 is fixedly installed with a belt pulley 62, and the belt pulley 62 is located at the same end as the motor 63.

[0035] Further, in the above technical solution, a plurality of cutters are installed on the slitting roller 4, the slitting roller 4 is a core component for slitting the ceramic diaphragm, the plurality of cutters installed on the slitting roller 4 can accurately cut the ceramic diaphragm, a grid frame is fixedly installed in the bottom opening of the dust hood 73, and the dust hood 73 can quickly capture the ceramic dust generated during the slitting process to prevent the dust from spreading to the surrounding environment. The shape and size of the dust hood 73 are carefully designed to ensure that its coverage range can effectively include the working area of the slitting roller 4, and the dust is collected to the maximum extent. The internal structure may adopt a special flow guide design, so that the dust-containing airflow can flow more smoothly into the dust suction pipeline, and the dust suction efficiency is improved. For example, a tapered inlet design can increase the airflow speed and enhance the suction effect on the dust.

The conveying roller 2 is stably conveyed to the slitting roller 4 direction under the action of the motor power, relying on the friction force between its surface and the ceramic diaphragm.

[0038] When the ceramic diaphragm reaches the slitting roller 4, the multiple cutters on the slitting roller 4 accurately cut the ceramic diaphragm into the required width under high-speed rotation. In the slitting process, the dust hood 73 quickly captures the generated ceramic dust by using the corresponding position of the feed port below it and the slitting roller 4.
